Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple nutrient solutions are used to provide complete nutrition, then plant growth requirements are met, but system complexity and ease of operation deteriorate

Engineering Contradiction:
Improvecomplete nutrition deliveryVSAvoidnumber of nutrient solutions
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple nutrient solutions containing different nutrients (macronutrients and micronutrients) into a single integrated nutrient composition. This merging eliminates the need to separately manage multiple solutions while ensuring complete plant nutrition, directly resolving the contradiction between complete nutrition delivery and system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single nutrient composition is designed to provide universal nutrition for plants by incorporating all essential macronutrients (N, P, K, Ca, Mg, S) and micronutrients (Fe, Mn, Zn, Cu, B, Mo) in appropriate concentrations. This multi-functional formulation replaces multiple specialized nutrient solutions, simplifying the system while maintaining complete nutritional support

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If multiple nutrient solutions are used to ensure stability, then nutrient compatibility is improved, but ease of operation and productivity worsen

Engineering Contradiction:
Improvenutrient stabilityVSAvoidnutrient solution management
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent merges multiple stable nutrient formulations into one unified composition that maintains chemical stability through proper formulation. The single composition eliminates the operational burden of managing multiple separate solutions while preserving nutrient stability through careful selection of compatible compounds and concentrations

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent optimizes parameters such as pH, ionic strength, and nutrient concentrations to ensure stability of all nutrients within the single composition. By adjusting these parameters, the formulation achieves chemical compatibility among all nutrients, maintaining stability without requiring separate solutions

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If multiple nutrient solutions are used to address material incompatibilities, then nutrient stability is improved, but device complexity and loss of time increase

Engineering Contradiction:
Improvematerial compatibilityVSAvoidtime to prepare and manage solutions
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent combines all nutrient components into a single pre-formulated composition that has been optimized for material compatibility. This eliminates the time-consuming process of preparing and coordinating multiple separate solutions, as all nutrients are already compatible and integrated in the single formulation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The nutrient composition is pre-formulated with all compatibility issues resolved during manufacturing. The preliminary formulation work includes selecting compatible compounds and optimizing concentrations to prevent precipitation or degradation, saving users time by eliminating the need for complex preparation procedures

Inventive Principle:
Principle #10Preliminary action
